==== Init scripts are applied to `buildSrc` builds

Init scripts specified using `--init-script` are now applied to `buildSrc` builds. In previous releases these were applied to included builds but not `buildSrc builds.

This behavior is now consistent for `buildSrc` and included builds.

==== Gradle no longer runs the `build` task for `buildSrc` builds

** configurations from the root project
** configurations from all subprojects
** configurations from `buildSrc`
** included builds configurations
** configurations used by plugins
* download all artifacts discovered during resolution
* compute the requested checksums and possibly verify signatures depending on what you asked
